Hallo.

My OS is Debian Sarge. I use the Sarge Backports Version of PHP 5.2.0. If the Zend Optimizer is enabled Roundcube just brings a balnk page. The error log got some seg faults. If i disable Zend it works. How do get Roundcube running with Zend optimizer enabled?

i guess it's a php trouble, not a rouncube one. try first

<?php echo "hello world"; ?>

zend optimizer, like other optimizer must be invisible, le php code doesn't care about optimizer. Specific code can use special feature, like shared variable, but, generic code doesn't.
